The issues had arisen when we're enumerating a large list of user variables in a loop to write midi data to Reaper's midi editor, and then giving Reaper not enough time to open and close the midi take.

We've fixed this by opening a midi take before the loop runs and closing a midi take after the loop, instead of doing it inside a loop. Hope this makes sense?

Here is a more illustrated example in "pseudo code". We did something similar to this.

def example:

for a, b in enumerate(some_array):
    for c, d in enumerate(another_array):

    self.do_something() 
    self.do_something_more() 

self.msg('test')

def do_something:

take = self.getActTakeInEditor()
midi = self.allocateMIDITake(take)

# do something to the midi take...

self.freeMIDITake(midi)

def do_something_more:

take = self.getActTakeInEditor()
midi = self.allocateMIDITake(take)

# do something to the midi take...

self.freeMIDITake(midi)

Ok, thanks for the details! Will be fixed for the next release ( r1138 ).

Also, yes, your new code totally makes sense performance-wise but it does not solve the bug being disccused here (just lowers the probability it occurs...)
